Diplomacy is broken

[Noir]

Welcome to the .org Corka,

I've read/heard that some modifications particularly tweaked that aspect of the game to be much better than as it stands in vanilla. It might help a lot to play with a mod in any case. You can find mods here:

and at the total war centre.

Many Thanks

Noir
